PWM Solar Controllers 30A 20A 10A 12V 24V Auto PV Solar Char Controller Back-light LCD Display Dual 5V USB Battery Regulator ,Easy to Use

4-Sta charging(Boost, ABS, Equalization,Float),and equipped with industrial-grade STM 8 microprocessor to prolong your battery life cycle.Dual USB can give your electronic product max 5V 2.5A. This solar controller backlight display PV/Battery/Load char and dischar parameter. like the fourth picture, adjustable Floating volta/LVD/LVR/Timer according needs with with power-off-memory function. This solar char controller fit for Lead-acid batteries(OPEN,L) with mutiple load timer.Load should be DC. For protecting the lifespan of your battery, once the volta of the battery drop below 8V, the solar controller will turn off automatically. Eight PWM char controller Protection:Power off memory /Dual MOSFET Reverse current /over heat /Under-volta dischar /short-circuit /open-circuit / over-load /over-charging protection.more safe for home, industrial,commercial etc.
